Journal ArticleDOI
Variation in survivorship of a migratory songbird throughout its annual cycle
TL;DR: Seasonal and annual survival estimates from resightings of colour-ringed individuals on breeding grounds in New Hampshire, USA and on winter quarters in Jamaica, West Indies from 1986 to 1999 were used to calculate warbler survival for the migratory periods.
Journal ArticleDOI
Individuals and populations: the role of long-term, individual-based studies of animals in ecology and evolutionary biology.
TL;DR: This review emphasises the unusual opportunities and productivity of long-term, individual-based studies and documents the important role that they play in research on ecology and evolutionary biology as well as the difficulties they face.
Journal ArticleDOI
Emperor penguins and climate change
TL;DR: The results indicate strong and contrasting effects of large-scale oceanographic processes and sea-ice extent on the demography of emperor penguins, and their potential high susceptibility to climate change.
Journal ArticleDOI
Predation risk and the cost of being fat
TL;DR: A link between fat reserves and predation risk is demonstrated by describing changes in body mass that have occurred in British populations of the great tit, Parus major since 1950, a period when the numbers of its principal predator, the spar-rowhawk Accipiter nisus, changed markedly.
Journal ArticleDOI
Co-feeding ticks: Epidemiological significance for tick-borne pathogen transmission
TL;DR: It is shown that a much wider range of natural hosts than was previously recognized may contribute significantly to the transmission of tick-borne diseases, and compare quantitatively the relative contributions made by the systemic and non-systemic transmission pathways.
